Reversible plow



UNITED STATES PATENT OFFICE.

BENJAMIN J. LESLIE, OF DE MOSSVILLE, KENTUCKY.

REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 235,156, dated December '7, 1880.

Application filed March 30, 1880.

To all whom it may concern:

Be it known that I,BENJAM1N J. LEsLIE, a citizen of the United States, residing at De Mossville, Pendleton county, Kentucky, have invented new and useful Improvements in Reversible or Hillside Plows, of which the following is a specification.

My invention relates to that class of plows in which a ,double-ended share having a pivoted and self-adjustable wing or extension of the mold-board is combined with a reversible beam, and its object is to improve the construction and utility of such implements.

To this end my invention consists, first, in an improved construction of the wing and its connection with the double share; second, in the provision and arrangement of a strengthening-brace to givesteadiness to the share; third, in the fastening devices for securing the swiveling beam in its ultimate position.

My invention is embodied in mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my improved plow complete; Fig. 2, a transverse section of the share, taken centrally, and showing the connection and lateral extension of the wing; v and Fig. 3, an under plan view of the beam and fastening devices.

Similar letters of reference indicate similar parts throughout the drawings.

A is the share or mold-board of the plow; B, the sheth or beam-supporting standard; 0, the movable wing, and D the draft-beam.

3 5 The share or mold-board Ais formed with a double end having two furrowing-surfaces, a

a, pointing in opposite directions, and a common landside, a. The sheth B is a single post or standard rising from the landside, and is turned off at its upper end to form a pivot, 11, for the swiveling beam D, as hereinafter more particularly described. The wing 0 consists of two somewhat triangular-shaped diverging plates laterally extended above, as shown in Figs. 1 and 2, and united toward their bases or pivot ends into one. The base is projected laterally on one side into a pivot, c, and at the other is notched, as shown at 0 or may there be also extended into a pivot similar to 0. An opening is left in the moldboard at the line of junction of the furrowing- (No model.)

surfaces of sufficient size to allow the wing O to rest in and project therefrom and oscillate freely on its pivots, which are held on one side under the mold-board a, and on the other in a bearing-socket, d, secured transversely across the opening of the mold-board, as clearly shown in Fig, 2. This mode of securing the wing O is not only much cheaper, but perfectly protects the parts from any injury or interference with their movement from dirt, &c., and at the same time the lower edge 'of the wing forms a stop against the under side of the moldboard to limit its movement in either direction, the surface edge of the mold-board always overlapping the wing, so as to allow the earth or sod to slide freely upon the wing. It also, by reason of the increased strength derived from a continuous support across the entire base of the wing, enables me to construct the wings with wide lateral extensions, (shown in Fig. 2,) and thus turn the sod completely and easily, which prior constructions have failed to do.

I construct the landside bar or plate of the plow and the sheth of one piece, using but one sheth, which is journaled at the upper end, I), to form a pivot for the beam, upon which it is secured by a nut and washer, thus forming a strong and cheap plow and a rigid beam-connection. This construction also enables me to use a light plow without sacrifice of strength. I employ also a strengtheningbrace, G, bolted to the under side of the plowbeam, forward of the sheth B, and extending rearward and downward, so as to embrace the sheth B just above the mold-board. The object of this brace, as will be obvious, is to transmit the draft-strain to a point as near the mold-board as possible, and avoid the necessity of using a heavy and clumsy sheth or standard. The brace terminates in a ring inclosing the sheth B, which is permitted to rotate freely within it, while it gives steadiness also to the beam and sheth connections.

The fastening devices for securing the swiveling beam to the sheth are as follows: Upon the sheth or standard B, upon the shoulder formed by reducing the upper or pivot end, is rigidly secured, horizontally, a longitudinal plate, E, at the ends of which are extensions 6 e, forming a jaw at each end of the bar.

When the plate E is in position lengthwise with the plow-beam, which rests upon it, a sliding bolt, F, having a squared end and moving in suitable yokes or guides, is moved into the opening between the jaws c e at one end of the bar E, and holds it and the plowshare in proper relation to the beam. The bolt may be Withdrawn and the plow turned around and secured in the opposite position by the bolt engaging the opposite end of the bar E.

It will be observed that the projections e e, at opposite ends of the plate E, and upon the landside of the plow, extend farther than the projections e e, and the guides of the sliding bolt are so arranged as to permit the boltF to be withdrawn only far enough to clear the shorter projections. By this means the beam can only be turned independently of the plow by turning the team on the land side-that is, upon the undisturbed ground-while the extension of thejaws eeforms a stop against the end of the bolt, to prevent movement in the other direction.

The rear end of the bolt is furnished with a handle, it, for convenience of its use by the attendant.

I do not claim, broadly, the use of hinged double wings in a reversible plow, as such, substantially, have been used in prior constructions.

Having described my invention, I claim and desire to secure by Letters Patent- 1. The wing C, constructed, as shown, with laterally-extended diverging sections 0, pivot c, and notch or pivot 0 in combination with the mold-board A, having an opening and socket, d, for the reception and play of the wing, substantially as and for the purpose specified.

2. The swiveling beam D, in combination with the sheth or standard B and brace G, encircling the standard, substantially as and for the purpose specified.

3. The combination of the plate E, having jaws e e projecting from its ends, the former projecting beyond the latter, with the bolt F, having a sliding movement limited so that the bolt may, when withdrawn, form a permanent stop to limit the rotation of the swiveling beam in one direction at either end of the plate E, yet when thrust forward engage between the jaws and prevent all movement of the swiveling beam, constructed and arranged as shown, and for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
